Car Seats in a Tesla: What Fits in Each Model, by Row
Every Tesla has lower car seat anchors in its two outer rear seats, and in the Model 3, Model Y and Model S the middle rear seat takes a belt-installed seat only. Three narrow seats fit a Model Y's rear bench on paper with about half an inch to spare, and the one hands-on Model Y report, from Australia, says three fit. This page sets out, model by model, which seats have anchors and tethers, what the owner's manuals forbid, the rear-seat widths against three narrow seats, and what the six-seat Model Y L and the three-row Model X offer a family with a third child.
